LightGBM

Track your trees with W&B.

Try in Colab

The wandb library includes a special callback for LightGBM. It’s also easy to use the generic logging features of W&B to track large experiments, like hyperparameter sweeps.

from wandb.integration.lightgbm import wandb_callback, log_summary
import lightgbm as lgb

# Log metrics to W&B
gbm = lgb.train(..., callbacks=[wandb_callback()])

# Log feature importance plot and upload model checkpoint to W&B
log_summary(gbm, save_model_checkpoint=True)

Tuning your hyperparameters with Sweeps

Attaining the maximum performance out of models requires tuning hyperparameters, like tree depth and learning rate. W&B Sweeps is a powerful toolkit for configuring, orchestrating, and analyzing large hyperparameter testing experiments.

To learn more about these tools and see an example of how to use Sweeps with XGBoost, check out this interactive Colab notebook.
